Can the human eye see a single photon?

Exploring the physics of color, the limitations of human vision, and the possibility of perceiving a single photon. Delving into the interaction of photons with the eyeball and the physics of color perception. Discussing the nature of light and the role of cones and rods in the retina. Exploring the experiment on blue tits and their invisible UV markings. Examining the challenges of perceiving a single photon and manipulating light sources. Delving into theories on when the wave function collapses and the concept of the human eye as a quantum detection instrument.
